BRIQUET-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 782,470, dated February 14, 1905.

I Application led May 12, 1904. Serial No. 207,706.

To a/ZZ whom it may concern:

molding or die ring within the interior of which and in its plane are disposed the main operating parts, including` the supply of material from which the briquets are formed; in

mounting this die-ring on a main impellingv gear-wheel concentric with thelatter and revolving on the same shaft on which is also sustained an abutting member to receive and absorb the main or final thrust of the pistons that compress the briquets, the whole being mounted and disposed in a narrow plane; also, in utilizing the effect of centrifugal force in filling the molds and in means to supply the material radially to the molds to secure the filling of the same aided by centrifugal force; means for preventing an overcharge of the same and to prevent disruptive strain on the parts, with other features and parts that form a part of this specification.

The objects of my invention are to dispose in a narrow plane all the operating parts of the machine, to absorb the principal strains in this plane and apply the strains centrally on the structure, to supply the material to the molds in the direction of centrifugal force, to

l reduce the machine to the smallest dimensions Fig. I, showing the driving-gearing and other parts visible in that plane.

In briquet-machines of the rotary type it is common to supply the material inwardly t0 the molds against centrifugal force, which is considerable when the machines are driven at full speed, also is common to provide an abutment for thrust outside the mold-ring difficult to resist by the framing because occupying about ninety degrees of arc. These and other impediments I avoid by the construction now vto be explained.

lis a main frame disposed in two parts cross-coined by struts 11 and disposed at each side of the mold-ring 2 and the main drivingwheel 3. This frame 1 receives in strong bearings the central shaft 4,'also the axis or pivot 5 of the strong lever 6, on which is mounted the pressing-wheel 7, that exerts the inal and intensepressure to form the briquets. Y

The main impell-ing gear-wheel 3 is mounted loosely on the central shaft 4 and is made integralv with or may be bolted to the mold-ring Y2. This gear-wheel 3 is driven by a pinion 8, shaft 9, gear-wheel 10, pinion 12, and a clutched pulley 13 or by any other suitable gearing of transmission such as -isemployed A in such cases. i

Through the rim of the mold-ring 2 are a series of radial holes 14, that form molds, and

in these are sliding plungers l5, disposed in one or more rows or tiers, according to the required size and capacity ofthe machine, two rows being shown in the present drawings. The holes or molds 14 can be made in the solid metal or be fitted with lining-shells of hard or non-corrosive metal andmay have a round, polygonal, or oval section. The plungers 15 are shown of cylindrical form, with convexly-formed heads 17, so they may turn `when in use to wear uniformly, and are preferably made hard at the ends to withstand abrasive wear on the material and against the guides 18 19 29 and the pressingwheel 7.

The culm or other material to be formed into briquets is supplied by any suitable means on the line a in Fig. II to the hopper 2O and passes down into the chamber 22, rest- IOO ing over and filling the molds 14 at the bottom by gravity and centrifugal force unless the material is in a plastic condition and will not fall or flow, in which case I employ rollers, as shown at23 in Fig. I, or other suitable means to insure charging. When the molds 14 are filled, they pass a fixed scraper 24, that slightly compresses the material in the molds 14 and produces a flush face to pass under the abutting member 28, where preliminary compression begins by action of the plungers 15, that are pressed inward by the volute guide 18, as shown in Fig. I. The plungers 15 being thus moved inward first by the volute guide 18 partially compress the material, then come in contact with the pressing-wheel 7, which without sliding action on the pins 15 exerts the final and intense force, reducing the material to the dimensions indicated at 27 and to a briquet, the inward pressure on the briquets being received on the member 28, that presents a concentric arc to the inner face of the mold-ring 2, as shown in Fig. I. When the plungers 15 pass the pressing-wheel 7 and the abutment member 28, they come in contact with the two eccentric guides 19 and 29, the former pressing the plungers' inward and discharging the compressed briquets, which fall into a hopper 30, from where they are conveyed to some place of use or deposit, as indicated by the line e in Fig. II. The eccentric guide 29 fits under the heads on the plungers 15, as shown in Fig. II, anddraws them outward into Contact with the concentric guide 82, as shown in Fig. I, leaving the molds 14 free for another charge from the chamber 22. In case of any metallic or other obstruction entering with the culm or entering the machine by accident, the lever 6 and pressing-wheel 7 yield to abnormal pressure by reason of the adjustable spring 33 on the tension-rod 34 to avoid fracture of the parts by overstrain. seen that the locus of principal strain falls within the continuous framing 1 and on the shafts 4 and 5, the latter being supported as indicated by dotted lines in Fig. I, also that the machinery is disposed in a narrow vertical plane, so the material and briquets are received and discharged by gravity.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

. 1. In a briquet-machine, a revoluble moldring, -a gear-wheel connected therewith, both mounted on a common shaft, means for driving said gear-wheel and mold-ring, the latter being provided with radial mold-apertures, means to supply material to said mold-apertures from the inside of the revoluble moldring, sliding plungers in said mold-apertures, with heads on the outside, eccentric guides outside of said heads to press the plungers inward, guides to move the plungers outward by In this manner it will be` engagement with the under sides of the heads, and a pressing-wheel outside of' the mold-ring, between said guides, bearing against said plunger-heads in succession to give the final comprnssive thru-sts thereto, substantially as specifie 2. In a briquet-machine, a fixed shaft, an annular mold-ring revolubly mounted thereon, means to revolve said mold-ring, the latter being provided with a series of radial moldapertures in which are sliding plungers with heads on the outside, means to move said plungers successively inward and outward, means to give a final compressive thrust on said plungers from the outside, a fixed abutment within the mold-ring to resist the thrust o f said plungers, and means to supply material to said mold-apertures from the interior of the mold-ring, substantially as specified.

3.
